Electric Motor
An electric motor is a device that converts electrical energy into mechanical energy. In today’s life, electric motors have numerous applications including in homes, commercial buildings, and manufacturing industries. An electric motor works on the principle of Ampere’s law which states when a wire is carrying an electric current, it generates magnetic field around itself. In other words, an electric motor is able to generate motion by use of magnets and therefore its whole operation is about magnets & magnetism.
Electric motors have been in use since 1800s and their efficiencies have been constantly improved. Most of these motors have their efficiencies ranging between 70% and 85%. Some of the energy is lost in form of heat and sound. It is also important to note that an electric motor is used to generate rotary or linear torque.
What are the main components of an electric motor?
An electric motor comprises of the following basic components:
Rotator: It is also called an armature. This is an electromagnet that is made when a thin wire is wound around a series of metal cores.
Rotor: This is the moving part of an electric motor that is used to rotate the shaft so as to produce mechanical power. Typically, the rotor comprises of conductors that are used to carry currents which interact with the stator’s magnetic field to produce forces that rotate the shaft. But some rotors contain permanent magnets and in that case the stator is used for holding the
